Used as a filter for light, this material could form the basis of handheld multispectral imaging devices that identify the “true color” of objects examined. “Such portable technology could have applications in a wide range of fields, from home improvement, like matching paint colors, to biomedical imaging, including analyzing colors in medical images to detect disease,” says Alexander N. Cartwright, professor of electrical engineering at the University at Buffalo and one of the researchers who led the study. Because the colors of the rainbow filter are produced as a result of the filter’s surface geometry, and not by some kind of pigment, the colors won’t fade over time. The same principle applies to the color of butterflies’ wings and to peacock feathers. Full story at Futurity. More research news from top universities. Photo credit: University at Buffalo | | | |
